Hi everyone, i have an issue with my model on LS-Dyna. I´m developing a model of a ball impact on ballistic gelatin as consecuence of free fall. Everything run OK, but the box of balistic gelatin suffer a plastic deformation wrongly. I attach three images, what has to be and 2 of what is happening(first the impact and then after relaxing time). I have a Material 10+eos as gelatin and Material 20 as the steel ball. Also have an automatic contact surface to surface, so i dont know what is happening. Anyone can help me?? thank you so much ! <3<\/p>\n
